To all whom it may concern.-

Be it known that I, GAsToN A. BRONDER, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Measuring-Drum, of which the following is a specification.

This invention relates to measuring-gates and its object is the production of a measuring-gate which can measure and discharge material from a receptacle and at the same time avoid the clogging of the said material with the moving parts of the invention.

The accompanying drawings show the invention applied to a coke or coal hopper, and it is represented to comprise a hollow drum with an opening in its shell arranged to operate with an opening in the hopper, the latter opening being never completely closed by any position of the drum. An apron bearing on the drum is hinged from the hopper and constitutes a secondary receptacle for any material that may tend to escape when the said material is being discharged from the hopper and into the drum.

Figure 1 shows a front View of the invention with a portion of a hopper. Fig. 2 is a side view of Fig. 1. Fig. 3 represents a section of Fig. 1 on the line 00 m. Fig. 4 shows a partial section of Fig. 2 on the line w 00. Fig. 5 is a top view of the measuring gate or drum. Fig. 6 is a section similar to that shown in Fig. 3 with the measuring gate or drum turned to a different position. Fig. 7 shows a section similar to Fig. 4 with a modification. Fig. 8 is a section of Fig. 7 on the line a :6 Fig. 9 shows a partial front view of the hopper and drum as modified.

A hopper is shown at A with the mouth or snout A, under which is journaled the measuring gate or drum B by means of the trunnions I), supported in the journal-bearing hangers C. An apron D is hinged on the pins d, that extend from the sides of the snout A. The said apron consists of the front (1 and the sides (Z which latter are generally curved, as shown at d, for a portion of their lengths, so as to ride or bear on the outer cylindrical surface of the drum B as well as the lower edge of the front (Z One of the trunnions b is extended and carries the coupling E, with which it is connected to the shaft b, that carries a pulley F for the chain F, and a journal-bearing hanger G supports the end of the said shaft. The chain F is generally fastened at one point on the circumferential face of the pulley, a sprocketwheel not being necessary, as the pulley is only required to be turned a portion of a revolution to open and close the opening a in the hopper.

One side A of the drum is cut away, as shown at a, so as to allow a small portion of the material in the hopper A to pass therethrough when the drum is closing the main portion of the opening a in the snout of the said hopper.

A shaker-chain A is arrangedto slide on the inside of the hopper near its opening or in its snout, as on the side A and extends through openings a in the side A*. The said chain asses under the guides a extending from t e side A and passes over the pulleys a which latter are journaled from the brackets a that extend from the hopper.

The drum B comprises the shell B, which partially surrounds the flanged heads B leaving an opening B leading into said drum. The flanged heads B extend into the opening B as shown at B so that the apron D will have a uniform cylindrical surface to bear on when the drum is being turned.

In Figs. 7, 8, and 9 two drums H and I, with their trunnions h in the same axial line, operate under the opening or snout of the hopper M. The trunnions h extend from the outer ends of the drums and are supported in the journal-bearing hangers J, extending from the said hopper M. A journal-bearing hanger J supports the trunnions 7%, extending from the adjacent ends of the drums, and a plate K, secured in the hopper M, divides the opening in the snout of the hopper and supports the said hanger J. A coupling is shown at L to connect one of the trunnions h with the shaft h which latter carries the pulley N, on which is fastened the chain N. A second pulley O, with chain O, is carried on the extension of the trunnion h, extending from the outer face of the drum 1, thereby securing means to oper ate the drums independently of each other.

An apron D is hinged from the hopper and bears on both of the drums, forming a secondary receptacle to prevent the spilling of any material while the drums are charged, and any material that finds its way into the said receptacle will finally enter the drums. The division-plate K bears on the edges of the drums H and I and preventsthe material escaping between the adjacent faces of the drums.

To operate the invention, the drum B is IIO turned so that its opening B faces the opening a" of the snout A of the hopper A, when the coke, coal, or other material contained in the hopper will fill the said drum, and thereby measure the quantity of material taken from the hopper. The drum is then turned about one hundred and eighty degrees to the position shown in Fig. 6, when it Will be emptied by reason of the opening B being now on the bottom, and the opening of the snout will be closed by the shell 13 of the drum. Next the drum is turned back to its original position, as shown in Fig. 3, by the chain F, when another charge will enter the said drum.

It will be noted that a full charge of the drum is taken from the hopper every time the drum or gate B is operated. In the modified form, Figs. 7, 8, and 9, either one of the drums can be operated by using the chain N or O. The sizes of the drums H and I can be of various capacity less than that when one drum is used to completely span the opening of the snout, and a predetermined quantity of material can be taken from the hopper by means of the drums or gates.

It will be noted that when a drum is turning in the direction of the arrow to close the opening in the end of the snout a little material can pass through the opening a in the side of the hopper, which prevents the material clogging the circumferential advance of the drum or gate when the edges of the openings in the drums pass the opening a in the side of the hopper. The little material that escapes by way of said opening a is entrapped upon the outer face of the drum by means of the apron D, and when the drum is turned back to be recharged the said mate rial will find its way into the drum. Should the material in the snout of the hopper become clogged, the chain A is pulled over the pulleys a to loosen the said material.

Having described my invention, I claim 1. The combination of a receptacle, a drum arranged to turn and, thereby open and partially close an opening in the receptacle, an apron hinged from the receptacle, and. arranged to bear on the gate, and form a secondary receptacle, around the opening in the main receptacle.

2. The combination of a hopper, a drum arranged to turn and thereby open and partially close an opening in the hopper, an apron hinged from the hopper, and arranged to bear on the drum and form a secondary receptacle around the opening in the hopper.

3. The combination of a hopper, a hollow drum having an opening in its shell journaled adjacent to an opening in the hopper, means to turn the drum to different positions, and

thereby open and partially close the opening in the hopper, an apron hinged from the hopper and arranged to bear on the drum and form a secondary receptacle around the opening in the hopper.

4. The combination of a hopper, a drum arranged to turn and thereby open and close an opening in the hopper, an apron hinged from the hopper and arranged to bear on the drum and. form a secondary receptacle around the opening in the hopper, and a shaker inthe hopper adjacent to the drum.

5. The combination of a hopper having openings, hollow drums each having an opening, with their longitudinal axes in the same axial line, j ournaled to partially bear against the edges of the said openings in the hopper, means to turn the drums to different positions independently of each other, and an apron hinged from the hopper and bearing on the drums.

6. The combination of a hopper having an opening; hollow drums each having an opening in their cylindrical surfaces and the axes in the same axial line journaled. under the opening in the hopper, a division-plate closing part of the said opening in the hopper, and bearing on the edges of the adjacent cylindrical faces of the drums, means to turn the drums to dil'l'erent positions independently of each other, and an apron hinged from the hopper, bearing on the drums and surrounding the opening .in the hopper.

7. The combination of a hopper, a hollow drum having an opening in its shell journaled to bear against the edges of an opening in the hopper, a shaker-chain in the hopper adjacent to the drum and extending through opposite sides of the hopper, the chain arranged to be pulled through the said opposite sides, trunnions on the drum, and means to turn the drum to different positions, to charge and empty the said drum.

8. The combination of a hopper, a hollow drum having an opening in its shell journaled to bear below an opening in the hopper, a shaker-chain in the hopper adjacent to the drum and extending through opposite sides of the hopper, pulleys journaled on the outside of the hopper to guide the shaker-chain that passes through the hopper, guides for the chain in the hopper, trunnions on the drum, a pulley supported on one of the trunnions, and a chain on the latter pulley.
